摘要： In a gyrocompass in which a gyro is housed in a gyro case with a spin axis arranged substantially horizontal, a container is provided for surrounding the gyro case and for containing a liquid. A suspension wire supports the gyro case within the container and a supporting device is provided to support the case with three degrees of freedom. A vertical follow-up device ensures that the container follows the gyro case around a vertical axis. A detector supplies a detected signal to the follow-up device to produce a follow-up error responsive to displacement and twisting of the suspension wire so that a damping torque is applied to the gyro case. A delay element supplies the detected signal to the follow-up device to produce a follow-up error therein.

摘要： This invention relates to a vibration-type gyro apparatus for measuring an angular velocity using the Coriolis force exerted on a tuning fork. The tuning fork has two vibrational members symmetric about a Z axis. The two vibrational members vibrate along Z axis and are displaced along a Y axis by the Coriolis force. Each of the two vibrational members includes a cantilevered tabular member arranged along an XZ plane and has a shape symmetric about the center axis thereof. Electrode sections are formed on the two sides of the vibrational members, and electrodes are formed in the internal space of a casing at positions corresponding to the electrode sections. The electrodes are arranged by being deviated outward or inward of the center axis of the vibration members with respect to the electrode sections. Each of the electrodes is supplied with a displacement detection AC voltage and a control voltage from a detection and drive circuit.
